In a year when Michael Lewis' book The Blind Side became a box office hit, the position that current NFL star Michael Oher helped to make more famous is now becoming somewhat of an obsession at the prep football level. The nation's consensus top player, Seantrel Henderson, is very much in the mold of Oher, who now protects Joe Flacco's back. There hasn't been a more coveted or hyped lineman in the past decade than Henderson, who hails from Saint Paul, Minn. http://feedads.g.doubleclick.net/~at...gaFQ3qyCc/0/dihttp://feedads.g.doubleclick.net/~at...gaFQ3qyCc/1/di
